DBR71205FU is a UL-approved normally closed high voltage reed relay designed for applications requiring very high isolation voltages. It features rhodium contacts with 5kV isolation across contacts, a 12V DC coil with 240O resistance, and PCB mount with flying lead HV connection. The relay offers low contact resistance of 50 mO max (15 mO typical), switching power up to 50W, and maximum switching voltage of 1000V DC/AC peak. With an operating temperature range of -20°C to +70°C and 17kV contact-to-coil isolation, this relay is suitable for high reliability applications such as cardiac defibrillators, test equipment, and high voltage power supplies.
